SIPI-ION.

To all whom it may concern:

Be it known that I, EGBERT C. COOK, a citizen of the United States, residing at Lakewood, in the county of Eddy and Territory of New Mexico, have invented a new and useful Siphon, of which the following is a specification.

This invention relates generally to siphons, and particularly to one adapted for use in irrigating land.

As is well known, in "certain sections of the United States artificial irrigation has to be resorted to. This is generally accomplished by digging ditches at intervals in a field, and then cutting outlets through the ditches to lead the water to the land to be irrigated. Of course, the bottoms of the ditches have to be higher than the adjacent land for this purpose. While efiicient in securing the results designed, this mode of irrigation is exceedingly expensive and requires the attention of many employees to retain the ditches in condition and to see that the gates employed for closing the outlet cuts are in proper working order. Moreover, as the escaping water cuts away the walls of the outlets, a waste of water results which is a serious matter, and moreover, to remedy the above defect, considerable 6X- pense ensues, by reason of the fact that workmen have constantly to be employed in building up or repairing the washed away portions of the outlets.

It is the object of the present invention, in a ready, efficient, thoroughly feasible and practical manner to obviate the above objectionable features, and further materially to reduce the labor incident to artificial irrigation.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a siphon, as will hereinafter be fully described and claimed.

In the accompanying drawings forming a part of this specification, and in which like characters of reference indicate corresponding parts, Figure l is a view in perspective displaying the siphon operatively positioned relatively to a ditch and to the land to be irrigated. Fig. 2 is an enlarged detail sectional view of a portion of the effluent leg. Fig. 3 is a similar view of a portion of the infiuent leg. Fig. 4 is a longitudinal sec- Specification of Letters Patent.

tional view through a slightly modified form of siphon.

As shown in Fig. 1, the siphon consists of an infiuent leg 1 and an eflluent leg 2, the two being disposed at an angle of about 40 degrees relatively to each other. These legs will, by preference, be constructed of sheet metal, such as galvanized iron, and will be connected at their meeting point by a band 3, which may be held in position by solder or rivets.

To render the apparatus operative under all conditions of use, it is essential that the inlet end of the infiuent leg be protected against the entrance of any substance that would tend to clog it. In the present instance two simple expedients are utilized for this purpose, the first of which consists in partially closing the intake mouth by two outwardly bowed metallic semi-bands 4, riv eted or otherwise secured to the leg, and the second of which consists in beveling the intake mouth at any desired angle to the length of the leg, both of which features are clearly shown in Fig. 3.

The outlet end of the effluent leg has combined with it a novel means to prevent backsiphoning and also to establish siphonic action in the device. This means consists of a tubular length of fabric 5 which may be of knitted hose or of one or more plies of heavy' canvas, and which is held assembled with the effluent leg by a band or wire 6. By preference, the leg 2 will be provided with a circumferential crimp or groove 6 adjacent to its discharge end to receive the wire, as shown in Fig. 4, thus to insure an airtight connection between the extension 5 and the efiluent leg, and also to secure a stable union between the parts.

In order to check the operation of the siphon without lifting the infiuent leg out of the water, a suitable air inlet is provided, which may be in the nature of a valve, or, as shown in Fig. 1, it may be an ordinary screw cap 7 which will engage with a nipple provided on the band 8 for the purpose.

In the form of invention shown in Fig. 4, in which only a portion of the effluent leg is displayed, it being understood that he entire length of the siphon will be constructed in the same manner, the effluent leg 8 is constructed of a length of hose, which may be either fabric or rubber, and which is held assembled against collapsing by a coiled spring 9. The extension or discharge mouth 10 is constructed in the same'manner as shown in Fig. 5, and is held in position by a band or wire 11.

In order to facilitate handling the device,

a handle 12 is provided, which is herein shown as a metallic band, secured to the efliuent leg, and provided with a suitable handhold, although if preferred a strap or loop may be employed, and will be found to secure'the object sought.

- In order to protect the member 5 from being cut by the discharge end of the eflluent leg, the margin of the latter is headed and wired, as shown at 13 in Fig. 2, the'b'e'ad being on the exterior of the leg, thus to provide a shoulder'to hold'the band or wire 6 from becoming detached, and thus dispense with the groove shown in Fig. 4.

In the use of the device, the entire siphon is immersed in the water of the ditch so that all the air is expelled, the vent 7 being sealed. The operator then grasps themouth piece 5 and squeezes it, so as to prevent the escape of'water and the entrance of air, and then lifts the efiluent leg, care being observed that the inlet end of the infiu'ent tube remains submerged. The siphon is then positioned upon the ridge R of the ditch,as shown in Fig. 1, and upon the mouth piece 5 being released, the water will flow on the land L. Should it be desired to check the operation of the siphon without removing it from the ditch, it'will only benecessary to loosen the screw cap whereupon air will pass into the interior of the siphon and thus stop its operation. The mouthpiece 5 subserves an other very important function namely, that of preventing back-siphoning by preclud ing entrance of air. This result is secured by making the mouth piece wholly of flexible material which, when the siphon "is in operative position, will flatten out and thus accomplish the object for which it is designed.

The'use of the siphon herein described will be found equally as efficient as the old methods heretofore in vogue, and which have been briefly outlined, and will enable one operator to accomplish more work with less waste of water than has been heretofore possible. a

While the siphon has been described as used for irrigation purposes, yet, as will be obvious, it may be employed in any situation where it may be found of practical advantage.

From the foregoing description of the invention it will be understood that the influe'nt end of the'leg 1,b'eing cut at an angle, the said leg need not be immersed in the water in the ditch D 'to any considerable depth as the plane of the said'end will be approximately parallel with 'the water surface in the ditch when the device is'in proper position, such for example *as shownin Fig. 1 ofthe'drawings. Itwill further be understood that by providing the semi-bands t,the said influent end of the leg 1 is prevented from coming itself into 'contact with the mud at the bottom of the ditch buton the other hand is supported above 'the'bottom.

and cloggingof the leg by the mud inthe ditch is in this'manner obviated.

I claim 1. In a siphon of the class'described, an influent leg having its intake end cut at an angle, andsemi-bands secured at the said end of the leg and extending in advance of its said angularly cut end.

2. In a siphon of the class described, an influent leg having its intake end cut at an angle, and semi-bands secured at the said end of the leg and extending in'advance of its said angularly cut end, the saidbands' being arranged in parallel relation with their bowed extremities terminating in a plane at an angle to the plane occupied by the said angular-1y cut end of the leg.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
